Hi Newsgroup, I am testing our Exchange implementation. But every time I am running jetstressUI with automatic tuning, the tuning process stops with the following errormsg: "Tuning process couldn't find suitable parametes, please use the suppress tuning to specify parameters" Any Ideas ? How I can prevent this error and do a successfully performace test? Thanks. Danijel
Hello Danijel, My answer assumes that you are using JetStress 8721 build http://www.microsoft.com/downloads/details.aspx?familyid=94b9810b-670e-433a-b5ef-b47054595e9c There are many times that JetStressUI fails to find a good test IO parameters to acheive the target IO. For most of these cases, the user has to find "test IO parameters" by monitoring the database and log disk latencies on his or her own. For me to better understand your system, I'd like you to post the text box of JetStressUI and JS_Config.xml.
